stmmac: move hw init in the probe (v2)
This patch moves the MAC HW initialization and
the HW feature verification from the open to the probe
function as D. Miller suggested.
So the patch actually reorganizes and tidies-up some parts of
the driver and indeed fixes some problem when tune its HW features.
These can be overwritten by looking at the HW cap register at
run-time and that generated problems.

stmmac: add the experimental PCI support
This patch adds the PCI support (as EXPERIMENTAL)
this has been also tested on XLINX XC2V3000 FF1152AMT0221
D1215994A VIRTEX FPGA board.
To support the PCI bus the main part has been reworked
and both the platform and the PCI specific parts have
been moved into different files.

stmmac: parameters auto-tuning through HW cap reg
New GMAC devices (newer than the databook 3.50a) have the
HW capability register that provides which features are actually
supported by the hardware.
On old devices many information have to be passed through the
platform, for example: enhanced descriptor structure,
TX COE etc. These are mandatory to properly configure the driver.
This remains still valid because the driver has to support old
Synopsys devices but now it's also able to override them using the
values from the HW capability register if supported.

stmmac: add CHAINED descriptor mode support (V4)
This patch enhances the STMMAC driver to support CHAINED mode of
descriptor.
STMMAC supports DMA descriptor to operate both in dual buffer(RING)
and linked-list(CHAINED) mode. In RING mode (default) each descriptor
points to two data buffer pointers whereas in CHAINED mode they point
to only one data buffer pointer.
In CHAINED mode each descriptor will have pointer to next descriptor in
the list, hence creating the explicit chaining in the descriptor itself,
whereas such explicit chaining is not possible in RING mode.
First version of this work has been done by Rayagond.
Then the patch has been reworked avoiding ifdef inside the C code.
A new header file has been added to define all the functions needed for
managing enhanced and normal descriptors.
In fact, these have to be specialized according to the ring/chain usage.
Two new C files have been also added to implement the helper routines
needed to manage: jumbo frames, chain and ring setup (i.e. desc3).

stmmac: protect tx process with lock (V4)
This patch fixes a problem raised on Orly ARM SMP platform
where, in case of fragmented frames, the descriptors
in the TX ring resulted broken. This was due to a missing lock
protection in the tx process.

stmmac: add MMC support exported via ethtool (v3)
This patch adds the MMC management counters support.
MMC module is an extension of the register address
space and all the hardware counters can be accessed
via ethtoo -S ethX.
Note that, the MMC interrupts remain masked and the logic
to handle this kind of interrupt will be added later (if
actually useful).

stmmac: support wake up irq from external sources (v3)
On some platforms e.g. SPEAr the wake up irq differs from the
GMAC interrupt source.
With this patch an external wake up irq can be passed through the
platform code and named as "eth_wake_irq".
In case the wake up interrupt is not passed from the platform
so the driver will continue to use the mac irq (ndev->irq)
